SIGNAL-STATION.

SPECIFICATION forming part of Letters Patent No. 698,942, dated April 29, 1902.

Application filed March l3 1901. Serial No. 50,902. (No model.)

To all whom it may concern:

Be it known that I, JOHN W. HARRISON, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Signal-Stations; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to signals, and has for its object an improved signaling device intended to be used in connection with a railway-station to indicate to the train-driver that there is a passenger at the station and that it is desired that the train stop at such station for the passenger. The signal-station is especially intended to be used with what are known as suburban trolley-lines, where the service is of a character such that the car is supposed tostop to take on passengers at frequent stations along the line. The station itself is small,'intended to accommodate only a few passengers, and is arranged to present asignal which is automatically actuated whenever the passenger stands inside the station or on the platform outside the station, and it is intended that the signal given shall indicate in which direction the passenger desires to travel, and consequently to indicate to the coming cars, from either direction or from both directions, which car is to stop.

In the drawings, Figure l is a side elevation of a station, showing the signal set to indicating position. Fig. 2 is a diagram indicating the means by which the signal is operated and the chain of connection between the operative means and the signal. Fig. 3 is a detail showing that part of the signal which is outside the station. Fig.4 is a detail, shown on a large scale, of the operative part of the mechanism. Fig. 5 is a detail showing the front view of the parts shown in Fig. 4. Fig. 6 is a plan of the station.

The station is a small building (indicated at A, Fig. 1) divided into two parts a and I), each of which is provided with a hanging floor. The floor may be hinged at the rear end by hinges a or it may be hung on stirrups at both ends. At the front end the floor a is hung by a stirrup c to a lever 07, and the end of thevlever opposite that one which is connected to the stirrup c is connected by a spring 0 to a fixedpart of the house, either to the side wall or to a side plank d, resting on the foundation or foundation-post e. The lever d is arranged to cause, the throwing of a signal and the closing of an electric circuit which brings about an illumination in a signal-box B on the outside of the station. At the same time that the current is turned through the lamps covers that had before been over the signal -apertures are thrown from the apertures and the lights are disclosed to view on that side of the house or on that side of the signal-box which is directed toward the coming car, which it is wished to stop.

As shown in the drawings, the lever (Z is made in the form of a wheel, to which are fastened crossed straps d and d and these crossed straps reach to and are secured to a second circular lever g, which is oscillated when the main lever dis oscillated by pulling downthe stirrup-link c. The stirrup-link c is pulled down whenever the passenger steps on the floor of the compartment a or whenever he steps .on the platformp in front of the compartment a. The platform 19 is sustained on armsp, that are secured to the floor inside the compartment a and extend through the front wall of the building A.

When the lever g is oscillated, an electric switch-arm g" is actuated, andwhen the floor is depressed, followed by the corresponding oscillation of the lever g and corresponding swing of the switch-arm g', electrical contact is made between the arm g and a terminal h, which closes a circuit from a proper source of electrical supply through the lights 1, 1 1, and 1. Two of these lights, 1* and 1 are signal-lights .contained in the box B. Two

riods that the station is unoccupied cover the apertures 1 and 2 through which light from the signals 1 and l shines out.

The means of actuating the semaphore-arm is a cord 2, linking the oscillating leverg to a similar oscillating lever 2 on the shaft. to which is secured the semaphore-arm S. The disks 7t 70 are held on hangers 1 and 2 pinned tothe side of the box 13, and they are actuated bya link 3 and a coupling-link 4 ,Which connects them pivotally to the semaphore--' is furnished with a back rail, so that persons cannot readily move from one section to the other in the station, but are required to remain in that position of the station where their presence will cause the signal to be shown which will give indications to the car they desire to stop, and the only attention required of the passenger is that he shall either step upon that section of the platform or enter that section of the station which lies toward the coming car which he desires to stop, and the signal continues in indicating position so long as the person remains either on the platform or in the station, and the signal drops "to indicate that there is no one present as soon as the passenger is out of the station and off the platform.

In giving the signal the lights are uncovered and the semaphore-arm is thrown with each actuation. Thus the semaphore-arm becomes a signal during the da'y-time and the lights become a signal during the night or during darkness.

What I claim is- 1. In combination with a station-building having two entrances, and a floor in two sections, each of which is independently movable, a seating on each floor-section arranged to confine a person within the station to the section to which he first enters, and a signaling apparatus connected with each of said sections and adapted to be actuated by the movement thereof, one of said signaling apparatus being adapted to signal a train coming in one direction, and the other to signal a train coming in the other direction.

2. In combination with a station-building provided with a floor in two sections, each of which is independently movable, a signaling apparatus connected with each of said sections and adapted to be actuated by the movementof the section with which it is connected, one of said signaling apparatus being adapted to signal a train coming in one direction, and the other to signal a train coming in the other direction.

3. In combination with a station-building provided with two entrances and a floor in two sections arranged so that a person entering by one entrance shall step upon one section and actuate it and a person entering by the other entrance shall step upon the other section and actuate it, a signaling apparatus connected with each of said sections and adapted to be actuated by the movement thereof, one of said signaling apparatus being adapted to signal a train coming in one direction, and the other to signal a train coming in the other direction.

4. In combination with a station-building provided with a floor in two sections, each of which is independently movable, a signal upon each end of said building facing toward the direction from which the trains come, and a mechanism connected with each of said signals and with each of said sections such that the movement of one of said sections shall operate one of said signals and the movement of the other section shall actuate the other of said signals.

In testimony whereof I sign this specification in the presence oftwo witnesses.

JOHN w. HARRISON.
